Close four findings from the health-score audit:
- Hypotension cliff: the below-floor branch reused the over-target table,
so 1 mmHg under the clinical floor dropped from 100 to ~81 — a 19-point
discontinuity. A dedicated under-floor curve now starts at 100 AT the
floor and descends smoothly (floor-10->70, -20->45, -30->20), so the
score is continuous on both sides of every boundary on both axes.
- Rollup vs live divergence: the graded BP score weighed a high-variance
day 1:1 on the rollup path (one per-day-mean pair) but N:1 on the live
path (N per-event pairs), drifting the pillar by up to ~20 points
depending on DAY-bucket warmth. gradeBpScoreFromSeries now takes an
optional per-pair count; the rollup path passes perDayPairCount so both
paths produce the same score for the same data.
- Resting proxy degenerate days: a day with fewer than three PULSE
samples no longer contributes a resting estimate, so a lone workout
reading can't masquerade as resting HR.
- Pulse-status proxy day boundary: thread the user's timezone into the
resting-proxy day-key so it buckets identically to the targets route.
Fairness anchors unchanged (134/87 -> 57, 165/105 -> 22).
Every surface that applied a resting-pulse target judged the raw PULSE
series against a resting band. Apple Health maps all heart-rate samples
— including workout HR — onto PULSE, and the resting figure onto a
separate RESTING_HEART_RATE type. A single workout emits hundreds of
expected-high samples, so the resting-target evaluation read a large
share "outside target" and tanked the in-target % / consistency even
when the clean resting series averaged a healthy figure.
Judge the resting band against a resting series. A shared helper prefers
RESTING_HEART_RATE; when the user has none it derives a proxy from the
low percentile of each day's PULSE samples, so a dense workout burst
sitting in the upper tail cannot drag the resting estimate up. Applied
to the resting-pulse tile + its consistency strip, the pulse in-target %
in the assessment snapshot, and the dashboard / sub-page classification.
Raw heart rate, where it is merely charted, no longer carries the
resting-band overlay. The doctor report is unchanged — it reports raw
heart-rate stats factually, with no resting-target judgment to mislead.
